Tutorial: How To Fix Model Identification

Error XXXXXX#XYZ Of WD Black I WithHDD Doctor for WD

UFix Procedures

This tutorial is intended to teach you how to fix the XXXXXX#XYZ problem which is detected

by our HDD Doctor of WD. The same procedures can also be applied to the case that your

HDD shows all exclamation blocks when you are using MHDD to get it scanned.

First, we get the bad HDD connected well to our HD Doctor for WD. At the position where

should be showing the model number, we can see a random number followed by "XYZ..." at

the end. This error happens possibly because its PCB was replaced before by someone else,

or the PCB itself has some problem, or the ROM chip on the PCB is having some problems. The

solution is to find an identical donor with the same model number, motor number and PCB,

then replace the bad PCB with the good one from the donor, and then upload the No.11 mod

which was backed up from the good HDD before the swap. The detailed vivid procedures are

presented below:

We can see from Figure 1 that there is a random model number end with "XYZ..."

Step 1:Find the identical donor with 3 identical parameters with the bad HDD: model number, motor

number and PCB number. Next, backup the firmware of the donor (See Figure 2).

Next, dismantle the good PCB from the donor and install it on the bad HDD to replace the

original one. Next, get the bad HDD connected well and upload the mod No.11 backup from

the donor. (See Figure 3)

Step 2:After the uploading, go to Other Operations tab, power off and exit the program. (See Figure

4)

Step 3:Launch the program again, we can see that this bad drive can be identified correctly, which

means we are done the fixing. (See Figure 5)

UImportant Notice

You must backup the firmware of the good drive first, otherwise the fixing can't be

proceeding.

After you finish the PCB swap, launch the program and wait for the "Ready" status and

click Auto Config, you should wait for 30 seconds or even 1 minute before its done. Dont

shut down the program forcefully, otherwise the fixing would be failed.

If you can't upload the mod No.11 to the bad drive after PCB swap is done, there mightbe some problem with the heads. Please refer to the related solutions for fixing head

problems.

After uploading mod No.11 is done successfully, you must power off the HDD, then exit

the main program then auto config to launch it again. If all the procedures are done

correctly, you can find that your bad drive has already been fixed.
